TOURNIQUET.

Application led February T 0 all whom 'it may concern.'

Be it known that I, JULIUS Noun, a subject of the Queen of the Netherlands, residing at The Hague, Netherlands, Buys Ballotstraat No. 95, have invented certain new and useful Improvements in llourniquets, ot which the following is a specification.

This invention is an improvement in surgical appliances to stop bleeding in operations or accidents, and has tor its object to prov-ide an improved bandage of simple form to tie limbs instantaneously and in the most simpleV manner, which can be rapidly applied and removed again, and which will remain securely in position.

I will explain the invention more fully with reference to the accompanying drawings in which:

Fig. 1 is an end view of the apparatus showing the course ot the straps, the spanscrew being in its most outward position.

Fig. 2 is a side view ot Fig. l.

Fig. 3 is a top plan view ot' Fig. 1.

Fig. 4 is a vertical section through Fig. 1, showing the spanscrew in its most inward position, the straps being lifted into their extreme position.

Fig. 5 is a modification of the apparatus shown in Fig. 1, also drawn in end view and the spanscrew being in its most outward position.

Fig. 6 is a side view of Fig. 5.

Fig. 7 is a top plan view of Fig. 5.

Fig. 8 is a vertical section through Fig. 5, the spanscrew being in its most inward position.

Fig. 9 shows the apparatus applied to tie off a limb.

Referringto the drawings 1 (Figs. 1-4) and 1'1 (Figs. 5 9) designates a case, having two slots 2 and 3 underneath, through which respectively the ends of a fixed short strap 4 and a long movable strap 5 run, and a third slot 6 on the top, in which a strong wedgeshaped clamp 7 is placed. The inner end of the short strap 4 is in a way fixed to the wedge 7, for example by sewing the strap round a pin 8 and then shoving it into the wedge. A hook 9 is xed to the outer end of the short strap 4. The long movable strap 5 is led through the upper slot and adjacent to the wedge 7, and an eye 10 is fixed to the lower end of this strap.

When both straps 4 and 5 are lixed round the limb by means ot' the hook and eye `9, 10, such as represented in Fig. 9, the loop 121925. Serial No. 8,613.

can be tightened up bysimply pulling the lupper free end of` the movable long strap 5 with the hand. The resultant pull is transmitted to the short strap 4 and thence to the wedge 7, thereby automatically securing the long strap 5 when it is released. Should it be necessary to instantly release the loop again for a moment, it is sufficient only to raise the wedge a little. The long strap having been pulled the spanscrew 11', which is placed on one side of the case, is screwedi inwardly to engagevpini, 12 (Figs. 1-4 and 9), or tube l12EL (Figs. 5-8) both carried by the screw, with the short strap 4 which in turn engages with the long strap 5. As the screw 11 is operated the straps are drawn into the case to the positions shown in Figures 4 and 8 and the circulation oi' the blood is thereby stopped. A very exact degree of tension can be maintained by the screw 11 which not only draws inwardly upon the straps but at the same time causes the wedge 7 to bind against the strap 5 and thus secure it in its adjusted position.

As everybody who uses the apparatus perhaps is not strong enough to initially pull the movable strap 5 sufficiently with the hand thus necessitating a maximum adjustment of the screw 11 before the limb is tied oit, it is proposed to provide a fourth slot 13 in the wall of the case 1 opposite to the screw. In the form of the invention shown in Figure 5 the side ot the case opposite the screw is entirely open, as indicated at 13a.

The apparatus enables a very quick and reliable underbinding of limbs. No indiarubber parts being used, the apparatus is always in a serviceable state. All parts can be taken to pieces, as for cleaning, disiniecting, or substituting. The straps are preferably made of woven material and the other parts of nickel plated stainless material.

By using this apparatus, pinching of the skin is entirely precluded.

Having now fully described my said invention what I `claim and desire to secure by Letters-Patentis:

1. A surgical appliance to stop bleeding, comprising a case having one slot on the top and two slots underneath, a wedge-shaped part mounted in the top slot and a short strap fastened to the wedge, passing through one slot underneath; a second strap passing through the second slot underneath and also through the top slot, a hook fastened to one strap and an eye fastened to the other one; and a screw by which the tension of the strap can be regulated and the wedge Xed,

arranged at one side of the case.

2. A surgical appliance to stop bleeding, comprising a case having one slot on the top and two slots underneath, a Wedgeshaped part mounted in the top slot, a shortstrap, a pin secured to said short strap and mounted in the wedge, the other end of said strap passing through one slot underneath; a second strap passing through the second slot underneath and also through the top slot between an edge thereof and the wedge; a hook fastened to one strap and an eye fastened to the other one; and a screw by which the tension of the straps can be regulated and the wedge Xed, arranged Vat one side of the case.

3. A surgical appliance to stop bleeding, comprising a case having one slot on the top and two slots underneath, a wedge-shaped part mounted in the top slot, a short strap, a pin secured to said short strap and mounted in the wedge, the other end of said strap passing through one slot underneath; and a second strap passing through the top slot between an edge thereoi` and the wedge; a hook fastened toone strap and an eye fastened to the other one; and a spansorew for regulating the tension of the straps and fixing the wedge, arranged at one side of the case, such screw having means engageable with one strap to cause the latter to engage the other strap when said screw is operated, said case having a fourth slot arranged in the wall thereof opposite to said meansand through which said means and portions of the straps may be projected.

In testimony whereof, I have signed my name to this specification at The Hague, this twenty-second day of January, 1925.
